design a semiconductor resistor with specified resistance to handle a given current denisty a semiconductor at T=300k Nd=5×10^15 cm^-3 acceptors are to be added to form a compensated p type material. the resistor is to have resistance 10kohm and handle a current denisty of 50A/cm^2 when 5v is applied

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?
